Fig. 26 is a perspective view of a slider adapted for use with the formof invention shown in Figs. 2 to 16 inclusive.

Referring' to Figs. 1 to a of .the drawings, the

numerals 10 and 12 designate stringers preferably made of woven materialhaving secured thereto cords 14 and 16 respectively to form beaded edgesto which the opposed series of locking elements 18 and 20 arerespectively connected. Stringer 12 is provided at one end with areceiving member 22. that cooperates with a complementary enteringmember 24 that is secured to one end of the stringer 10 to provide withreceiving member 22 an end closure for the stringers. A sliding device26 is carried by stringer 12 and is adapted to be positioned at theclosure end to receive the entering member 24 and to eflect a lockingengagement between the receiving and entering members in a mannerhereinafter described.

The receiving member 22 is preferably formed from a strip of sheetmetal, from which a stamping as shown in Fig. 8 is out, whose sidesbeing provided with transverse aligned cuts 28 and 30 will allow thesplit portions of each side to be folded in opposite directions to formangular side plates 32 and jaws 34. As best shown in Fig. 22 these sideplates are formed to provide a sheath 36 that is adapted to be securelyclamped around the corded edge of the stringer 12 and with parallelextensions or tabs 38 that are spaced to receive therebetween thestringer 12 to which they are secured by a rivet 40 or the like. Thesheath 36' is preferably of the thickness of the interlocking members soas to pass freely between the walls'42 and 44 of the sliding device. 26that is manually operated to lock and unlock the locking elements 18 and20, by a to-and-fromovement, respectively. The jaws 84 are spaced andhave their ends abutting to form a socket to receive a complementaryengaging portion of the entering member. For purposes of preventing thesliding device from passing off the receiving member, the Jaws areformed to have an overall dimension greater than the spacing between thewalls and thus serve as a stop toprevent the removal of the slidingdevice from stringer 12 at that end.

The entering member is also formed from a 'piece of sheet metal, fromwhich a blank as shown in Fig. 'l is punched and formed. The sides ofthe blank are L-shaped and folded back upon themselves to form anL-shaped member with side plates 46 and tabs 48 in spaced relation toreceive the end of stringer 10 to which the tabs 48 are attached by arivet 50. The side plates are similarly shaped and provided with lugs52. In their folded position they provide an engaging hook formed bylugs 52, a spacer portion 54 and a camming head portion 56.

The Bilge-81 8 portion 52 is hook shaped and extends along the innerside and from the outer end of the L shaped'member and is adapted toengage with the socket formed by arms 34 of the receiving member in sucha manner that the inner sides of the receiving and entering members willbe capable of assuming a parallel relation in the locked positionthereof and relative longitudinal movement of these parts will bepreadjacent these parts will assume the proper position for interlockingenga ment. The thickness of the engaging portion 52 is such that it willfreely pass between the flanged sides 56 and 60 of the sliding device.

The spacer portion 54 is preferably a continuation of the enga portionand is longer than the spaced flanged sides 58 and 60 and'thin enough topass freely therebetween.

The camming head portion 56 is formed by making the sides 46'rounded attheir upper ends and laterally projecting from that portion of the sidesthat constitutes the spacer portion. The face 62 of the cam is arcuate.The rounded sides of the head portion are sufllciently spaced toconstitute a sheath for the stringer and the end of the cord 14 whichterminates short of the stringer end, which is cutaway along its innerlower edge corresponding to the position of thespacer portion. Thecamming portion of the entering member has a thickness greater than thespace between the flanged sides of the' slider but less than the spacebetween the walls 42 and 44.

As shown in Fig. 23, the flanged sides 58 and 60 of the slider have cutaway portions 61, which extend for a suflicient length so that the headportion 56 may freely pass between the walls 42 and 44. It will beobvious that when the sliding device is moved forward the enteringmember will be permitted to move laterally into the sliding device andthe hooked end will be actuated in fully locked position by thecoactionof the flanged sides 58 and 60 and the cam surface 62. when thesliding device is moved to its lowermost limit of travel and the opposedinterlocking members are disengaged the stringer 10 may be readilydetached from thestringer 12 by a lateral movement of the enteringmember through and away from the sliding device.

In looking the ends of the stringers together the slidingdevice ispassed over the receiving member and is brought to rest .by its outerend abutting against the jaws of the socket, the entering member is thenpassed laterally and at an angle into the sliding device with the hookin partial engagement with the socket and with the head portionpartially within the sliding device. By moving the sliding deviceforward, the hook will be actuated into complete engagement or lockedposition with the socket by the camming effect of the cam surface andthe inner faces of its corresponding flanged side walls and the twoseparable parts will be brought into substantially parallel relationwith each other and the inner edges of the flexible stringers.

In Figs. 9 to 16 I have shown a modification of 24 and serve as guidesand cooperate with other portions of the receiving and entering membersfor locking the same together. The flanges preferably, but notnecessarily, extend across the width of the sliding device for a purposehereinafter described.

In this variation the receiving member 80 is to limit the movement ofthe entering member,.

the spacer portion 92 of which is adapted to be received in the spacebetween the tabs 82 and 64. These tabs are provided along theircorresponding inner and outer edges with cammed surfaces 94 and 96respectively so that when the spacer portion of the entering member isinserted between the tabs, the flanges 76 and 78 will first engage theirrespective cam surfaces 94 at a point inwardly thereof with the loweredge of the spacer contacting with the lowermost part of the lugs, whilethe cammed surfaces 62 of the head portion 56 will engage with theirrespective surfaces 96 at a point outwardly thereof and as the enteringmember is turned the pivot point of the entering member changes alongthe surface of the tabs until the flanges bear along the entire surfaceagainst the cam surfaces 94 and the cam surfaces 62 will have movedalong their corresponding surfaces 96 to eifect a wedging or lockingengagement between the receiving and entering members.

The slider member used with this form of the invention is shown in Fig.26 and is constructed identical to that above described in connectionwith Figs. 1 to 8 except that its outer end is formed with an arcuateportion 96' corresponding to the edges 94.

In the operation of this device the slider is moved to a position whereit is stopped by the engagement of the point of the tongue 98 of theslider with the surfaces or edges 96. The thickness of the tongue andthe angular surfaces 100 hold the slider in a predetermined angularposition corresponding to the angle which the entering member will mostlikely assume immediately prior to its insertion laterally between theflanges of the slider and the tabs of the receiving member 6 as shown inFig. 14. When the entering member is in this position, the flanges '76and 78 are in engagement with the corresponding arcuate ends of both theslider device and the receiving member and as the entering member isturned by hand the sliding device moves upwardly, bringing the cut-awayportions 61 out of registry with the cammed head portion 56, as shown inFig. 13, and thus preventing the entering member from slipping out ofpartial engagement with the receiving member. A continued movement ofthe slider will cause the lateral flanges 58 and 60 to engage with thecammed surfaces 62, thus turning the entering member into completelylocked position, as shown in Fig. 9.

A further modification of my invention is shown in Figs. 1'1 to 21. Inthis embodiment the receiving and entering members are constructed in amanner similar to that described in connection with Figs. 1 to 8, thesemembers being formed from blanks as shown in Figs. 20 and 21respectively.

The receiving and entering blanks are formed with cut-out portions 102and 104 respectively, so that when their sides are folded back uponthemselves along the lines 106 and 108 notches are provided to receivecomplementary locking members 110 and 112 respectively. Locking member110 is formed with spaced upper and lower flanges 114 that are disposedin overlapped relation with corresponding areas of the side plates ofthe entering member 116 and are secured thereto preferably by welding.Likewise locking member 112 is provided with upper and lower flanges 118that are similarly secured to the side plates of the receiving member120,. The superposed upper and lower flanges of the locking member 112serves as a stop for limiting the movement of the slider 26. Theengaging portion 122 is similar in construction to the interlockingelements 18 and 20, whereas the engaging portion 124 is formed with twospaced iaws 126 and 128, the former being provided with a roundedrecess, and the latter with a rounded projection between which theengaging portion 122 with its corresponding recess and projection isreceived. It will be obvious that disengagement of these interengagingportions can be effected only by an angular movement in acounter-clockwise direction.

It will be noted that in Figs. 1, 9 and 1'! that the corded edge of thetape on the entering or male side of the connecting parts has itsterminusinside the upper cylindrical partof the connecting member, asindicated by dotted lines in each instance.

It will be obvious that the invention is not to be restricted to theprecise constructions herein shown and described since many of thedetails, such as the structure of the stringers interlocking members andslider will necessarily vary or may be varied according to theparticular uses for which the fastener is designed and the constructionof the end attaching means of each stringer may also be varied by thoseskilled in the art, it

being intended that my invention be limited only by the scope of theclaims.
